The D555066 SWITCH AS-EMERGENCY is the Doosan replacement component for the emergency stop circuit on a range of electric counterbalance forklifts.

Quality and Reliability

Because the emergency stop is the last line of defense in a hazardous situation, switch quality matters. The Doosan D555066 is made to the original Doosan specification, with contact materials and actuation characteristics intended to deliver consistent performance over repeated emergency-stop cycles. Using a part built to the manufacturer’s drawing helps ensure correct fit, correct wiring connections, and dependable operation – rather than the intermittent behavior that worn or low-quality switches often develop over time.

Installation and Maintenance Tips

• Always isolate and disconnect the battery before removing the old emergency stop switch.
• Photograph or label the wiring before disconnection so terminals are reconnected correctly.
• Install the D555066 SWITCH AS-EMERGENCY securely in its mounting location and confirm the button actuates freely.
• After installation, test the circuit: with the truck powered, press the emergency stop, verify that the truck shuts down completely, then reset and confirm normal operation.
• Include the emergency stop in routine inspection schedules, checking for physical damage, sticky actuation, or evidence of overheating at the terminals.
